Abstract: ABSTRACT         A dispensing control and display system for fluid products is disclosed which is adapted to control the operation of a number of dispensers from a remote location and also provide a visual dis-play at the remote location of quantity and cost data for the fluid being dispensed by each of the dispensers.  The system utilizes pulse code and multiplexing in a telemetering system that requires little modification of the dispensers themselves, which may be gasoline pumps or the like.  The system uses existing power con-ductors for transmitting information between a dispenser control unit associated with each of the dispensers and a central control unit at the remote location.  Each dispenser control unit responds to an individual identification code signal sent by the central con-trol unit and transmits the data to the central control unit which is then received and forwarded to and displayed by a corresponding console control unit.  The identification code signals permit the system to operate with a single carrier frequency.  The system in-cludes features that insure accurate display of the cost and quantity by saving the data for retransmission in the event the system deter-mines that the data was not properly transmitted.  The operation of individual dispensing units may be interrupted and thereafter resumed by an operator at the remote location if desired, without affecting the display of the data.

Abstract: ABSTRACT OF THE DISCLOSURE A circuit for monitoring conduction of a phase controlled, alternating current switch, e.g., a thyristor switch, looks at the voltage across the switch.  This voltage has a high dv/dt whenever the switch stops and starts conducting current.  The voltage detected from across the switch is processed as follows:  it is differentiated to produce a train of voltage spikes of very short time duration and some lesser voltages; the lesser voltages are removed; the spikes are then amplified and extended in time duration; and finally the time extended spike are integrated.  The integrated voltage is a train of alternate positive and negative voltages averaging zero during normal switch operation.  However, when the switch conducts one of the half cycles only, the integrated voltage rises in one polarity sense depending upon the half cycle conducted.  A control circuit becomes operative upon the integrated voltage attaining a predetermined value to initiate a control function

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for separating from a mixture, seeds such as wheat, barley or oats from wild oats which includes feeding the mixture to a moving inclined surface having a pile with fences disposed above the surface and at an angle to the direction of movement of the surface, the wild oats being carried upwards by the pile and the others being discharged at the bottom.  In one arrangement a rotatable brush is disposed upwardly of each fence to rotate against the moving surface and remove the wild oats or other unwanted bodies from the pile of the surface passing these onto overlapping separating plates which direct the unwanted bodies downwards to an exit path.  Depressions beneath the moving surface permit the latter to deflect, to allow any unwanted bodies which find their way beneath one brush to pass under the fence.

Abstract: ABSTRACT OF THE DISCLOSURE   A rock bit assembly for drilling holes in the earth's crust has an integral bit body connectable to a drill string and a number of rotatable cutter cones.  Two rows of ball or roller bearings connect each cone to the bit body.  Each cone is formed with an inner shaft extending along the center axis of the cone and the inner races for the bearings are mounted on this shaft.  The bearings are located in an outer race which is connected to the bit body and is disconnectable therefrom.  Disconnection of the outer race results in the disconnection of the respective cone, bearings, and inner races.

Abstract: AUTOMATIC CAPACITOR WINDING MACHINE           Abstract of the Disclosure An automatic capacitor winding machine has a retractable bifurcated arbor and vertically movable clamps to grasp the ends of the capacitor dielectric layers and carry those ends to a point below the retracted arbor.  The bifurcated arbor is registered in its retracted state with its slot parallel to the dielectric layers.           The arbor is then extended and grasps the dielectric layers between its tangs.  The pressure grasping the dielectric layers is partially removed to allow the arbor to rotate and pull the dielectric layers from between the clamps.  A stripper washer is provided to freely rotate on the arbor with limited movement parallel to the axis of the arbor and with a relatively small clearance between the washer's inside surface and the arbor's outside surface.  Photo-electric means are provided to accurately detect the location of the first tab (terminal) to time the insertion of the other tabs.  A reciprocating blade severs the dielectric layers after the capacitor is wound.  Further, a roller wets the outer surface of the capacitor to prevent its unraveling.  As the arbor is retracted, the wound capacitor bears against the stripper washer and is stripped from the arbor.

Abstract: ABSTRACT OF THE DISCLOSURE         The glass tempering system disclosed includes a furnace having an elongated heating chamber in which a horizon-tal roller conveyor oscillates a sheet glass load between oppo-site ends of the chamber in an end-for-end manner.  The glass oscillation shortens the furnace length necessary to heat the glass to its quench temperature while still maintaining a suffi-cient speed to prevent sagging between the conveyor rollers.          Preferably, the length of the oscillating movement is longer than the length of the glass load so that no one roller is continuously supporting the glass.  A load station at one end of the furnace includes a horizontal roller conveyor driven by the same electric motor drive mechanism as the furnace conveyor during an index cycle so that the furnace receives a sheet glass load to be heated while simultaneously indexing a heated load outwardly through its other end to a horizontal roller conveyor of a quench unit.  A second electric motor drive mechanism drives the quench unit conveyor in an oscillating manner so that the glass is tempered in a uniform manner by a quenching air flow.  The two electric motor drive mechanisms are electrically coupled during the index cycle so that a tempered sheet glass load is conveyed from the quench unit to a horizontal roller conveyor of an unload station as a heated sheet glass load is conveyed to the quench unit,  The conveyor of the unload station is driven by the quench unit drive mechanism during the index cycle to receive the tempered sheet glass load.  Each of the conveyors includes a pair of continuous drive chains constantly driven by their associated drive mechanisms and supporting their associated conveyor rollers during the index cycle so as to frictionally drive the rollers.  After the index cycle, the rollers of the load and unload station conveyors are lifted off their respective drive chains by hydraulically actuated cam arrangements so as to remain stationary during the glass oscilla-tion and enable operators to unload the glass that has been tempered and also load glass to be tempered,

Granted: 1981-01-13
Abstract: Abstraction of The Invention An optical waveguide includes a core of high purity fused silica, a cladding of high purity fused silica and a protective coating of metallic glass.  The protective coating is applied as a liquid which contracts more than the glass after it solidifies to place the surface of the glass cladding under compression.  Because the waveguide will break only under tension, the force of compression must be overcome before the waveguide can be fractured thereby strengthening the waveguide considerably.  The metallic glass coating provides further advantages of abrasion protection and the prevention of fatigue.
